I've been attempting to bundle and deploy the develop branch Foreman on top of Apache/Passenger on Ubuntu 12.04 beta. I keep coming up against this error when I run the db:update:

undefined method `[]' for #<ActiveRecord::Reflection::AssociationReflection:0x7f781a5dbb20>

Full call and trace:

  @

I've tried a great deal of hokus-pokus, including changing gem package versions and git submodule checkouts, all to no avail. I admit my understanding of rails and vendoring is fairly limited, so I apologize if this is something stupid. Please let me know what else I need to provide.

Thanks,
Ryan
